Hello Everyone, I am trying to create a cross compiler using gcc-3.4.2, using the binutils given in the (http://www.opencores.org/projects.cgi/web/or1k/gnu_toolchain_port). I am running into the following difficulty (please see below as I have cut and pasted the result that I get). It is having troubles compiling the libgcc2.c. The below is the result I get right before the makefile crashes. I know some of the "#defines" used in the or32.c from the previous version have changed and I have updated them using the gcc internals manual. I have updated the config.gcc and all the configuration files that need to be updated according to the gcc manual to the best of my knowledge. I have also verified that the makefile (or configure script) does capture cross assembler and loader correctly. I don't know what is going wrong. I have also unsuccessfully tried using GDB to try to pinpoint the problem. It is configured using the following line. configure --target=or32-uclinux -prefix=/tmp/opt/or32-uclinux --with-local-prefix=/tmp/opt/or32-uclinux/or32-uclinux --with-gnu-as --with-gnu-ld --enable-languages=c Any help is appreciated. Thanking You, Yours Sincerely Balaji V. Iyer. PS: I have replaced my absolute directory path with "~" in the below output snippet right before cut and pasting. ======================== MY OUTPUT ERROR =============================== mkdir -p -- libgcc if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi /tmp/or1k/b-gcc-3.4.2/gcc/xgcc -B/tmp/or1k/b-gcc-3.4.2/gcc/ -B/tmp/opt/or32-uclinux/or32-uclinux/bin/ -B/tmp/opt/or32-uclinux/or32-uclinux/lib/ -isystem /tmp/opt/or32-uclinux/or32-uclinux/include -isystem /tmp/opt/or32-uclinux/or32-uclinux/sys-include -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I~/gcc-3.4.2/gcc -I~/gcc-3.4.2/gcc/. -I~/gcc-3.4.2/gcc/../include -DL__mulsi3 -xassembler-with-cpp -c ~/gcc-3.4.2/gcc/config/or32/or32.S -o libgcc/./__mulsi3.o /tmp/or1k/b-gcc-3.4.2/gcc/xgcc -B/tmp/or1k/b-gcc-3.4.2/gcc/ -B/tmp/opt/or32-uclinux/or32-uclinux/bin/ -B/tmp/opt/or32-uclinux/or32-uclinux/lib/ -isystem /tmp/opt/or32-uclinux/or32-uclinux/include -isystem /tmp/opt/or32-uclinux/or32-uclinux/sys-include -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I~/gcc-3.4.2/gcc -I~/gcc-3.4.2/gcc/. -I~/gcc-3.4.2/gcc/../include -DL__udivsi3 -xassembler-with-cpp -c ~/gcc-3.4.2/gcc/config/or32/or32.S -o libgcc/./__udivsi3.o /tmp/or1k/b-gcc-3.4.2/gcc/xgcc -B/tmp/or1k/b-gcc-3.4.2/gcc/ -B/tmp/opt/or32-uclinux/or32-uclinux/bin/ -B/tmp/opt/or32-uclinux/or32-uclinux/lib/ -isystem /tmp/opt/or32-uclinux/or32-uclinux/include -isystem /tmp/opt/or32-uclinux/or32-uclinux/sys-include -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I~/gcc-3.4.2/gcc -I~/gcc-3.4.2/gcc/. -I~/gcc-3.4.2/gcc/../include -DL__divsi3 -xassembler-with-cpp -c ~/gcc-3.4.2/gcc/config/or32/or32.S -o libgcc/./__divsi3.o /tmp/or1k/b-gcc-3.4.2/gcc/xgcc -B/tmp/or1k/b-gcc-3.4.2/gcc/ -B/tmp/opt/or32-uclinux/or32-uclinux/bin/ -B/tmp/opt/or32-uclinux/or32-uclinux/lib/ -isystem /tmp/opt/or32-uclinux/or32-uclinux/include -isystem /tmp/opt/or32-uclinux/or32-uclinux/sys-include -O2 -DIN_GCC - DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I~/gcc-3.4.2/gcc -I~/gcc-3.4.2/gcc/. -I~/gcc-3.4.2/gcc/../include -DL__umodsi3 -xassembler-with-cpp -c ~/gcc-3.4.2/gcc/config/or32/or32.S -o libgcc/./__umodsi3.o /tmp/or1k/b-gcc-3.4.2/gcc/xgcc -B/tmp/or1k/b-gcc-3.4.2/gcc/ -B/tmp/opt/or32-uclinux/or32-uclinux/bin/ -B/tmp/opt/or32-uclinux/or32-uclinux/lib/ -isystem /tmp/opt/or32-uclinux/or32-uclinux/include -isystem /tmp/opt/or32-uclinux/or32-uclinux/sys-include -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I~/gcc-3.4.2/gcc -I~/gcc-3.4.2/gcc/. -I~/gcc-3.4.2/gcc/../include -DL__modsi3 -xassembler-with-cpp -c ~/gcc-3.4.2/gcc/config/or32/or32.S -o libgcc/./__modsi3.o /tmp/or1k/b-gcc-3.4.2/gcc/xgcc -B/tmp/or1k/b-gcc-3.4.2/gcc/ -B/tmp/opt/or32-uclinux/or32-uclinux/bin/ -B/tmp/opt/or32-uclinux/or32-uclinux/lib/ -isystem /tmp/opt/or32-uclinux/or32-uclinux/include -isystem /tmp/opt/or32-uclinux/or32-uclinux/sys-include -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I~/gcc-3.4.2/gcc -I~/gcc-3.4.2/gcc/. -I~/gcc-3.4.2/gcc/../include -DL_muldi3 -c ~/gcc-3.4.2/gcc/libgcc2.c -o libgcc/./_muldi3.o ~/gcc-3.4.2/gcc/libgcc2.c:0: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.

if i understand correctly you are doing your own port ? if
so why don't you try opencores gcc-3.4.2 ? (it works for me without
problems you mention, but in case you would found them i'd be happy to
look into them)

best regards,

Hello Matjaz,
Opencores used gcc3.2.3 (atleast it wa the only version I found in the
CVS directory) and I need 3.4.2 because there are a lot of
haifa-scheduler optimizations available in the 3.4.2 that is not
available for 3.2.3

thanks,

Balaji V. Iyer.
